Application filed June 22, 1920. Serial No. 390,941).

To all whom t may concern:

Be it known that I, JAMES B. Mason, Jr, acitizen'of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Automobile-Bumpers, of which the-following is a specification.

This invention plates to automobile bumpers of the kinfi in which the bumper is spring-supportedor provided with cash ioning means whereby the shock ofe collision is to some extent reduced.

According to my present invention, 1 pr vide the-bumper bar with rcarwardly ex tending arms which are rigidly attached to the bar and which operate telescopically in brackets attached to therur springs or to other parts of the automobile frame. The arms are guided in the brackets and between the brackets and the bar, I interpose curved, metallic springs whibh bear against the front of the brackets and have asliding engage meat at their ends with the rear face of the bumper bar.

In the accompanying drawings Figure 1 is a perspective view of a. bumper embodying my improvements, showing how it may be attached to an automobile.

Fig. 2 is a ,plan View of the same and illustrates the action of the cushioning devices under certain condition.

Fig. 3 is a detail sectional view, showing how the rear'wardly extending arms of the bumper bar are guided and held in the brackets which support them.

Fig. 4b is a perspective view, showing separately a bumper bar with its arm, the spring which engao'es the bumper bar and the bracket into which the arm of the bar extends.

The bumper bar A may be of any usual form. It is provided with two rearwardly extending arms B which may be to the bar in any suitable way, in the manner shown.

Each arm B supports a spring C which is a curved. metallic spring having an open ing 0 through which the arm B extends. and having at each end a shoe m which is adapted to engagethe bar A and to have a sliding connection therewith endwlse of the bar,

attached preferably braeket D which is adapted to be Each arm B extends into a socket (Z in a secured to the frame of an automobile. As shown, it is secured to one of the springs l3 thereof by bolts The socketed portion of each bracket is formed with elongated, longitudi.- nal slots adapted to receive a cross pin c, which pin is adapted to pass through 2. hole I) in the arm When assembling the parts after the arms B are attached to the her they are passed through the holes a in two curved springs C and each arm is then passed into a souket d of one of the brackets, then the pin 9 is inserted and when this is done at each end of the bar the latter is properly supported and the springs are held in place and cannot be detached from the brackets or from the bar. But inasmuch as the springs can yield and their ends can slide on the bar, and inasmuch the arms. can more endwisc in the sockets, a strong and. eliicieut cushion for the bumper vided,

l ip it indicates a change in position of the parts which would occur if one end of the bumper came in contact with an obstruction, and it will be observed that readily adapts itself to the conditions, being flattened, out to some extent. the shoes a: sliding on the bar in suchmanncr to prevent any undue strain oh. the springs.

he springs are so constructed as to return the bar to normal position when the obstruction is removed.

I claim as my intention:

1. An automobile bumper, comp ising a bumper bar having rearwardly-e. ending arms, curved. metallic springs through which the arms extend and which have shoes at their outer ends having a sliding connection with the bar. and means for supporting" the arms from the frame of an. automobile.

2. An automobile bumper, compil brunpcr bar having;- rearwardl gr e arms. curved metailic s tirinpg's throi the arms extend and which have at their out. it ends shoes having a sliding" engagement with the bar, brackets having" sock "i into i "ch the arms extend and in which they I and means For holding the arms in the sockets.

3. An automobile bumper, comprisi the spring hill eeive the rear ends of the urn. and means for holding the arms in the soekets hnt which permit the arms to slide in the soekets. 10

In testimony whereof I have hereunto subscribed my name.
